Switched Linux distros to Suse 10.1; outboard hard drive no longer accessible
Folks, I've just switched from Ubuntu to Suse 10.1. An outboard USB hard drive (Maxtor 300 GB) no longer seems to respond to mount/umount commands (as root), although it did under Ubuntu. I'm trying to find a way to recover it without losing the data on board (it's my backup). More specifically, when I run fdisk -l, I get: Disk /dev/sda: 300.0 GB, 300090728448 bytes 255 heads, 63 sectors/track, 36483 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 36483 293049666 83 Linux dmesg give me: Vendor: Maxtor Model: OneTouch II Rev: 023g Type: Direct-Access ANSI SCSI revision: 04 SCSI device sda: 586114704 512-byte hdwr sectors (300091 MB) sda: Write Protect is off sda: Mode Sense: 24 00 00 00 sda: assuming drive cache: write through SCSI device sda: 586114704 512-byte hdwr sectors (300091 MB) sda: Write Protect is off sda: Mode Sense: 24 00 00 00 sda: assuming drive cache: write through sda: sda1 sd 2:0:0:0: Attached scsi disk sda sd 2:0:0:0: Attached scsi generic sg0 type 0 usb-storage: device scan complete *But* >mount /dev/sda1 gives me: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so So, when I run dmesg | tail, I get: sda: Mode Sense: 24 00 00 00 sda: assuming drive cache: write through sda: sda1 sd 2:0:0:0: Attached scsi disk sda sd 2:0:0:0: Attached scsi generic sg0 type 0 usb-storage: device scan complete martian destination 0.144.60.17 from 192.168.0.1, dev wlan0 martian destination 0.144.60.17 from 192.168.0.1, dev wlan0 FAT: bogus number of reserved sectors VFS: Can't find a valid FAT filesystem on dev sda1. Is this drive toast? Or are there specific steps I can take to make things right enough to recover the data (and even make the entire drive useful again!)? With best regards, Pete -- Peter N.

This uses information from /etc/fstab my guess is that in fstab you have an entry for sda1 that says "vfat" or "msdos" or something. My guess is also that the file system on this disk isn't a microsoft file system. Try mount /dev/sda1 /mnt By passing both device and mount point, you are forcing mount to ignore fstab, and actually try to detect which file system is in use. If you know which file system it is, you can also give it as -t <file system> to mount

Try
mount /dev/sda1 /mnt

Anders, Many thanks; that did it. I presume all I need to do is edit fstab and change the file system label to linux (which is what dmesg shows)/ Pete -- Peter N.
